I came across Sudoku a week ago, and I started to solve puzzles using Augusj's Simple Sudoku solver.I always let the program update the pencil marks automatically for me.I feel sometimes that it is doing most of the work, since I'm able to solve hard puzzles from papers in less than 10 minutes.

What do you think of letting the program pencil-marking for you ? Does it simplify too much the solving process ? Is that how you solve your own puzzles ?
